This scatter plot visualizes weekly temperature readings from San Francisco, sourced from the Data Canvas Sense Your City dataset. The visualization displays temperature against time, with each circle representing a temperature measurement at a specific timestamp. Built with React and D3 v5, the example uses `scaleTime` for the x-axis and `scaleLinear` for the y-axis. The SVG rendering includes custom axis components and circle marks, with tooltips showing the day of each data point through D3's `timeFormat` function.
